Environmental Cleanup at Terminal 117

The Terminal 117 cleanup site (T-117), located on the west bank of the Lower Duwamish Waterway in South Park, is a joint cleanup project by the Port of Seattle and City of Seattle. This site was identified for early cleanup (before the larger river cleanup) because the upland property, river bank and sediments in the waterway have high concentrations of PCBs (polychlorinated biphenyls), dioxin/furans and other contaminants. T-117 is designated as an Early Action Area as part of the Lower Duwamish Waterway Superfund Site listed by the U.S. Environmental Protection Agency (EPA) under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA).

The Site's History

T-117 has a long history in the Duwamish. The site was originally used for asphalt manufacturing, which left behind soil contamination. The Port acquired the site in 2000 and several cleanup actions have resulted since. Find the complete T-117 story and historic timeline here.

Community Outreach

In early 2010, members of the T-117 cleanup project team began visiting with local groups and citizens regarding the PCB cleanup of T-117 and the adjacent streets and yards. The Port of Seattle is responsible for cleanup of T-117 sediments and upland property and the City of Seattle is responsible for cleanup of streets and yards. They are developing plans for how the cleanup will occur. This work is directed and overseen by EPA. The Engineering Evaluation and Cost Analysis (EE/CA) describes the contaminants at the site, the location and concentrations of the contaminants, and options for how to clean up the site. You can access a copy of the EE/CA and other technical documents here. The public is invited to comment on the EE/CA from June 7 to July 7, 2010.
